Description of the Related Art An apparatus for winding and printing a printing plate or a blanket around the outer peripheral surface of a cylinder of a rotary printing press according to the prior art is disclosed in, for example, Japanese Patent No. 2956026. The stretching device disclosed in Japanese Patent No. 2956026 will be described with reference to the reference numerals shown in the drawings of Japanese Patent No. 2956026. A printing plate or blanket, ie, a plate, stretched on a cylinder by the stretching device will be described. The printing cylinder, i.e., a bent end is formed by bending both sides so as to match the angle formed by the side wall surface of the slit mounted on the cylinder and the outer peripheral surface of the cylinder. The other bent end is bent at substantially the same angle as the obtuse side of the slit, and the leg at the other bent end is provided with a number of rectangular openings. ing.

可能に挿入されている。Further, in the disclosed tensioning device for tensioning a plate, an axial slit formed in a cylinder of a rotary printing press, which is opened on an outer peripheral surface and formed inward in a radial direction, is provided on a cylinder. A hole is formed at the bottom for inserting an axial tension spindle, into which the tension spindle is rotatably inserted.

Can be Then, the plate is mounted on the outer peripheral surface of the body with tension by being wound around the rotating tension spindle from the other bending end side.

曲がり可能になっている。The means for attaching the other bent end to the tensioning spindle is provided by a plurality of square openings in the legs of the bent end, and an elastic square tongue, one surface of which can contact the inner edge of the opening. A number of rows of strips, i.e., comb-like leaf springs, are provided in the grooves of the V-shaped cross section of the tensioning spindle. That is, the tip of the tongue of the strip whose base is fixed to the bottom of the groove can be bent in a state where the tip of the tongue protrudes from the outer peripheral surface of the tension spindle.

After the tip of the tongue enters the opening at the bent end of the plate, further rotation of the tensioning spindle causes the tongue to be angularly displaced while warping and bending after one surface of the tongue contacts the inner edge of the opening. It is drawn into the slit by its elasticity. Then, an appropriate elastic force of the tongue piece is applied to the bent end portion, and the plate is stretched on the outer peripheral surface of the body.

The tip of the tongue is released to the back of the slit so that the tongue is no longer bent and the tongue is extended.

It is pushed out to. As a result, the plate at the opening of the slit is lifted away from the outer peripheral surface of the trunk, a gap is formed between the plate and the outer peripheral surface of the trunk, and the operator can remove the plate from the trunk.

The extension device to be installed
There are the following problems. 1. After inserting the plate attached to the torso into the slit provided on the outer peripheral surface of the torso, rotate the tension spindle, and insert the tip of the elastic tongue attached to the tension spindle into the plurality of openings at the plate bending end, Since the opening and the tip of the tongue are each square and both are positionally controlled by the width across flats, even if the plate is slightly shifted and inserted into the slit, the tongue does not enter the opening and the plate is mounted. If the width of the opening of the plate bending part is increased to avoid such inconvenience, there will be a large difference in the mounting position of the plate. May need to be redone, and in any case, the burden on the operator.

The shape of the slit provided in the trunk is formed outside the outer peripheral surface of the winding tension spindle insertion hole provided in the trunk, one of the side wall surfaces is in contact with the outer peripheral surface, and it is also appropriate in the circumferential direction. It is notched and connected. The bent end of the plate inserted into the slit is inserted outside the outer periphery of the tension spindle inserted through the tension spindle insertion hole.

トの外へと押し出すものである。The plate is pulled into the slit by utilizing the elastic deformation of a tongue piece having a base fixed in the tension spindle and the tip protruding from the outer peripheral surface of the tension spindle. For removal,
With the further rotation of the tension spindle, the tongue piece is once released from the plate and released to the back of the slit, and then the tension spindle is rotated in the reverse direction to push the plate out of the slit by the back surface of the tongue piece.

つてしまうおそれがあつた。[0012] However, the tongue attached to the tension spindle is permanently deformed by the repeated attaching and detaching operations of the plate, and the plate is attached with uniform tension due to the difference in the amount of deformation of each tongue. If the amount of deformation is large, the tip of the tongue cannot contact the plate, and the plate may not be able to be pulled into the slit and pushed out of the slit. Atsuta.

た。Further, the tongue piece is deformed or broken, so that it takes time to replace the tongue piece and to perform maintenance / inspection of the tension spindle, and it is not possible to improve the work efficiency. Further, the shape in which the slit and the tension spindle insertion hole are combined is relatively complicated and requires a lot of processing time.

The plate can be mounted on the outer peripheral surface of the body with uniform tension, and the plate can be pushed out of the slit of the body reliably when removing, so there is no need for repair, maintenance and inspection work. There is a demand for a plate mounting device and a plate that can be mounted on the plate mounting device, which has a simple shape in which the combined shape of the plate slit and the tension spindle insertion hole is simple and easy to process.

着体は印刷胴の外周面に巻き付けられた状態になる。The mounting of the mounted body on the printing cylinder is performed as follows. The first bent portion of the mounted body is inserted into the groove so as to be hooked on the edge of the printing cylinder. Then, when the printing press is started and the printing cylinder is rotated at a low speed, the mounted object starts to be wound around the outer peripheral surface of the printing cylinder. When the rotation of the printing cylinder is stopped at a position where the printing cylinder has rotated about one turn, the mounted body is wound around the outer peripheral surface of the printing cylinder.

At this time, even if the second bent portion is slightly displaced in the axial direction or does not completely enter the groove, the contact portion of the pin and the locking hole is circular, so that the pointed end of the pin is in the locking hole. If the pin is slightly inserted, the outer peripheral surface of the pin comes into contact with the inner peripheral surface of the locking hole, and the locking hole of the second bent portion is fitted into the pin with the angular displacement of the pin, and the second bending is performed. The part is drawn into the back of the groove.

面から離隔させる。Then, at a position where the rotational force of the rotational force applying means and the tension of the mounted member are balanced, the rotation of the locking shaft is stopped, and the mounting of the mounted member on the printing cylinder ends. The detaching operation of the mounted body mounted on the printing cylinder rotates the locking shaft in a direction against the rotational force of the rotational force applying means. The locking shaft passes through the predetermined rotation position, during which the pin comes out of the locking hole of the second bent portion, and then the second surface pushes the tip side of the second bent portion to form the second bent portion. The vicinity of the base of the folded part is separated from the outer peripheral surface of the printing cylinder.

After pulling out the second bent portion of the mounted body from the groove, the locking shaft is rotated according to the rotational force of the rotational force applying means until the rotational force disappears, and the operation ends.
